#21866 Remove AtomPub from core – WordPress Trac. Pappnasen. There have been bugs for years, yes. But they could have been fixed. Instead, AtomPub is being removed - but completely ignoring that the old WordPress XMLRPC stuff doesn't do the same thing - for example, it doesn't provide proper metadata updates for media uploads, which will result in only being able to use the AtomPub Plugin to sync images from Lightroom to WordPress with an export service in the future. There are still one or two things in this area that don't work properly, which is why I have always preferred to work with AtomPub from Lightroom. Now I can look forward to having to overhaul my entire image workflow after WordPress 3.5.
